Ferrari 275 GTB/C

308 GTB 3.5L Engine On Dyno

Here, at last, is a 275 engine that makes some genuine power. This 275 GTB/C two cam engine was built specifically for vintage racing. The cam is fairly radical, which hurts torque, but this engine loves to rev. Light weight valve train, aluminum flywheel, and titanium rods all contribute to this racy engine.
